How do we know that Jesus is the only way to be saved?

The claim of Jesus as the only way to salvation is a foundational doctrine in Christian faith. In John 14:6, Jesus explicitly states, 'I am the way, the truth, and the life; no man comes unto the Father, but by me.' This proclamation indicates that access to God and eternal life is reserved solely for those who come through Him. This exclusivity of Christ underscores the necessity of recognizing our inability to save ourselves; only through faith in His redemptive work can we receive salvation.

Moreover, the teaching in Luke 13 emphasizes the importance of striving to enter through Christ as the straight gate. The awake spirit in a person, causing them to seek, ask, and enter into relationship with Christ, is indicative of being granted spiritual life by God. Scriptures, including Romans 10:9-10, reinforce that belief in the salvation work of Christ leads to righteousness and a confession of faith for salvation. The assurance of being saved is rooted not in personal merit but in the completed work of Jesus, validating Him as the only way to God.
